Referring to Fig. 9 the coin detector is posi-- tioned'and secured in place in a cash register designated in its' entirety by the numeral I 60.. An inlet opening I62 is shown for the conduit; I63, which extends to the flange 45 of the inlet; conduit .40 of "the coin detector. The side walls; of the housing of the coin detector are again indicated at 2|. Brackets I66 hold the housing of the coin detector in place in the cash register.

"We may suppose a genuine silver dollar coin D: is passed through the inlet opening 46, Fig. 1 to enter the main inlet conduit 40. The said dollar D v drops into the upperend of the conduit 13, Fig. 3' of the conduit lever 10. The weight of the coinswings down all the conduitlevers in the di- Fig. 6. The coin D then.

On th discharge of the genuine silver dollar? vers, are all'swun original positions by their counterweights.

oin is shown at T, which exg 1113 to their If the coin is underweight-the operator inorder to remove the coin fromthe detector bears on the disc handle 64, and the release lever 50 bears against the pin "88, and thereby all the conduit levers swing down as shown -in-Fig. '6, and-=the coin rolls from the-conduit 13 f the lever into the discharge chute-25. When the operator releases the disc handle 64, the counterweights cause the conduit levers to swing to their original positions as indicated in Figs. 3 and 4. When the conduit levers swing up the pin 88 bears against the release lever 60, which in turn bears against the spring 92, which latter functions as a shock absorber.

If a silver half dollar coin H passed through the inlet opening 46, to enter the main inlet conduit 40, the half dollar coin H drop into the conduit I03 of the second conduit lever I00, and if a good coin it swings down the conduit levers I00, I20 and I40 in the direction of the arrow I15. The coin H passes through the clearance opening 15a of the conduit I3 and rolls from the conduit I03 of the lever I00 into the discharge chute 25, from which latter it can be easily removed. If the half dollar coin H is underweight, the conduit levers I00, I and I40 will not swing enough to permit the coin to roll from th conduit I03 of the lever I00. In such a case to remove the coin from the detector the operator bears on the disc handle 64, and the release lever 60 bears against the pin 88, and thereby the conduit levers swing down as shown in Fig. 6, and the coin rolls from the conduit I03 of the lever I00 into the discharge chute 25. When the operator releases the disc handle 64, the counterweights swing all the conduit levers to their original positions as indicated in Figs. 3 and 4.

If a twenty-five cent silver coin Q is passed through the inlet opening 46 to enter the main conduit 40, the twenty-five cent coin drops into the conduit I23 of the conduit lever I20, and if a good coin swings down the conduit lever I20 and also the fourth conduit lever I40, in the direction of the arrow I15. The coin if of the required weight passes through the clearance opening I05a of the conduit I03 of the lever I00, to drop from the conduit I23 of the lever I20 into the discharge chute 25, see Fig. 1.

If the twenty-five cent coin is underweight, see Fig. 2, the conduit levers I20 and I40 will not swing enough to permit the twenty-five cent coin to roll from the conduit I23 of the lever I20. In such a case to remove the coin from the detector, the operator bears on the disc handle 64, as described for the uppermost and second conduit levers and the coin then rolls from the conduit lever I20 into the discharge chute 25.

If a ten cent silver coin T, is passed through the inlet opening 46 to enter the main conduit 40, the ten cent coin '1 drops into the conduit I43 of the fourth conduit lever I40, and swings down the lever I40, in the direction of the arrow I15, and if the coin is of sufficient weight the coin rolls from the conduit I43 into the chute 25.

If the ten cent coin is underweight the conduit lever I40 will not swing enough to permit the ten cent coin T to roll therefrom. In such case the operator bears on the disc handle 64 to remove the coin as described for the other conduit levers.

It will be noted that when the conduit levers swing down, see Fig. 6, the pin 88 will contact with the hook end SI of the release lever 60 and prevent the conduit levers I0 swinging too far. The contact of the pin 80 with the hook end GI causes-the positive discharge of any oiwthecoins from thecondult levers.
